Podman is a containerization tool developed by RedHat to act as a drop-in replacement for Docker. This requires no virtual hardware, operating system, or virtual kernel. With this technology, virtualization occurs at the host level. This technology has been highly adopted in the past decade with tools such as Kubernetes, Podman, and Docker playing a significant part.Ĭontainerization is the packaging of a portable computing environment that contains everything an application needs to run, from binaries to dependencies. One solution to this challenge was the introduction of a virtualization technique known as containerization. Due to the increasing complexity of applications in infrastructure, many system admins and developers find it hard to manage the environments which may require a lot of resources and hence expensive.
